Unfortunately, common names usually give no information about chemical composition. To describe the atomic makeup of compounds, chemists use systematic methods for naming compounds and writing chemical formulas. In this chapter, you will be introduced to some of the rules used to identify simple ...

Why do some things like epsom salt, gypsum and calcium acetate have that discardable part to the right (*XxnXxn), but other things like K2O or calcium nitrate (Ca(NO3)2) don't? It reflects their composition. Some salts are hydrated - that is, they contain water molecules in their crys...
